Find the dependent child images on Docker

When you try to remove the docker image with the following command

docker rmi 6795374be8c1

Sometimes you might be facing below error:

Error response from daemon: conflict: unable to delete 6795374be8c1 (cannot be forced) - image has dependent child images

Below is the Docker command line used to find the dependent child images

Format:

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since= -q)

Example:

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since=6795374be8c1 -q)

Result:

sha256:1d1f94c972fc8d75a34135f9ff551617680c508f7ad17efda09048b4e805g1w3

Here sha256:1d1f94c972fc8d75a34135f9ff551617680c508f7ad17efda09048b4e805g1w3, the bold value is your dependent child image

i want to delete image what i dont use, but the image have child where the child image is use...

docker inspect --format='{{.Id}} {{.Parent}}' $(docker images --filter since=6795374be8c1 -q)
This will also return not dependent images, but that were created since specified one was. You have to additionally filter with parent id like here.
